Just an anecdote: at the holiday party hosted by my wife's company this last December--they're an enterprise software vendor just beginning to build an internal BI function--when asked what I did, only "analytics" or "databases" elicited any sort of recognition from any of the dozens of people I introduced myself to that night. As for the other terms you list, I would NEVER use any of them in a conversation with the business, unless I wanted to end that conversation :-) Your terms are, however, excellent questions to ask of candidates during job interviews.
